Answer:
B
Explanation:
y = mx + b where m = slope and b = y intercept.
The slope = 1/2 so you can eliminate C.
You can plug (-2,-4) into each equation and see which one works.
OR
y = 1/2x + b
Plug in (-2,-4) for (x,y) and solve for b.
-4 = 1/2(-2) + b
-4 = -1 + b
-3 = b.
So the equation would be y = 1/2x - 3. B
